F ig. 5 is a detail vertical section of the preferred form of drip and air pipe arrangement .of one of the auxiliary cooling chambers. n o o o s i Eig. 6 1s a vertical sectional view of a s modification of the invention.

4"Referringgg` to the drawing, in which similar Characters of reference designate corresponding parts in the several views thereof, the numeral 10 indicates a cold storage charnber, located between the ordinary `floor `11 and a cement basement iioor 12, of a building, the latter floorfbeing continuous with Extending Vclinedcement` iioor19. The forward end of the inclined Hoor 19 is arranged toproject beyond and overlie `the adjacent founda-A tion wall 13, and is formed with a drip .dis-` charge outlet 20 cfa pipe 21, whichprojectsdownward` into a well orchamber 22,

formed in advance of thecooling chamber 10.

s `'iupported `on `the inclined ,cemento floor i 1.9, of the ice chamber 18,or disposed in Vgrooves 23, formed therein ,for the o purpose, .is a Acoil 24, havinga connection, at one end, with an air supply 25, which maybe in the form ofa fan blower, drivenin any suitable manner,A orA byineans of an electricinotor ..26, and, atits other end with a discharge pipe 27, `the latter descending into the well 22`and having an angular discharge` nozzle portion28, disposed in the plane `of thechannel 14:, and discharging longitudinally thereof. The grooves 23 are preferably of a depth to admit of the sections ofl the air cooling coil;24 being positioned therein, so

thattheirtop surfaces are withinthe plane s of theinclined surface of the floor 19 to 'prevent the possibility Fof their being injured by the ice, when the same is lbeing The `fan blower 25 is inclosed by a housing 29, which'is provided with a cover-30, and an opening 31 through which is passed the drive beltV 32, connecting the blower to the motor.

Rising vertically of the cooling chamber 10, and corresponding in number to that of `the traps 15, are a pluralityV of `cement stand-pipes 33 which project through the floor 11, and each terminates in a flared portion 34, the purpose of which will be hereinafter" described; Extending the length of the channel 14, and inclosing the same, are one or more cover sections 35, so as to provide a duct for leading the cooled air to the stand-pipes 33. The forward end 36 of the cover section 35, is inclined upward, as shown, to direct a portion of thetcool air into the npperpart of the well 22, where it may be admitted to the cold storagechamber 10 through a valve 37 provided for the purpose in a partition wall 38, which separates "the well from said cold storage chamber. `The stand-pipes 33 may be provided with valves 39 fory the purpose of cutting' off the air passing through the channel`14.

A pipe 40 Connects the fan blower 25 to the rear of the channel 14, whereby the warmer air collecting at this pointV may be withdrawn andpassed again into the coil 24.

i Inaddition to the foregoingconstruction,

the invention contemplates the use of one or more refrigerator units 41, 42 and 43, of which there may be a number of such units to correspond to the number of stand-pipes 33, each being positioned over one of the .latter, and having the lower, end of their or' storage compartments v(not shown), the llatterbemg separated by a Vpartition wall 45` drip pipes supported within `the flared portion 34 thereof. e "These refrigerator units may be of the ordinary or usual construction, but are preferably of the construction as set forth in Lettersratent No. 1,209,171, and eared December 19, 1916, in which case they comprise an upper ice chamber 41, and a pair Extending upward within the partition wall 45, ofthe unit 41, is a drip pipe 46 which opens'through the bottom wall of the ice Tchamber 44, and inclines downwardly there- `from and projectsthrough the bottom wall of the refrigerator. The drippipe V 46 is provided with traps 47 adapted to receive the drip water and retain any and all sediment, which may be removed through the sual capped outlets 48, when necessary or desired.'

In the unit 42, the drip pipe comprises two elbow sections 49 and 50, each provided with a capped outlet 51, and are connected together by means of va union 52, the lower section 50 being further connected, by Vrim-3ans of a nn'ion 53 to a "discharge section 54,

which is passed through the 'bottom wall of the refrigeratorpand is supportedin the flared Vportion 34 of a stand-pipe.-

In the unit 43, the drip pipe 55 isangularly bent toprovide ai tortuous passage,

` ai'idisalso provided with soil traps 56, similar to those of the unit 41.

In the units 41 and 43, air passes upward through the drip pipes 46 and 55 in direct contact with the drip water, which is discharged into the stand-pipes 33, and into the traps 15 at the bottom .of the latter. The air, to be admitted to the refrigerator units may be taken direct from the channel 14, entirely, or the lower portions of the drip pipes may be provided with flared ends 57 formed with openings so as to admit the lcool air circulating beneath the refrigerator ted to the cold storage chamber 10` through the valve 37 in the partition 38. The' cold drip water, from the` mainice chamber or house, is discharged into Vthe well`l22V and flows through the longitudinal` channel 14 and lls the several traps I15, thereof." The drip water from the Vrefrigerators 41, 42 and 43 discharges through the "stand-pipes 33 and empties into the respective traps thereof. The flow of4 this drip water, however, may

be checked by thefvalves 39, so that its cooling eil-ject is transmitted to the cooling chamber 10, through the cementpwalls of the standipes. A free and continuous circulation'oi the cold air is'inaintainedthroughout thestorage apparatus by means rof the` return'pipe 40.` A portionof the aircircu- 'lation is also `maintained'through the channel inv contact with the drip water from the main ice chamber, asfwell asthat from the several refrigerators,l so` thatthe entire'cooling effect of the latteris utilized.

In theV modiedformof the invention, as shown in Fig. 6,l the air 'cooling coilf60,"located in the inclined floor 62, of the ice house 61, is provided` with a dependingdischarge pipe 63, which is continuous with or connects to a second" air cooling coil64 supported Within the lower portion ofja relatively deep well 65,. thelatter havingits walls formed of ycement and continuous with the foundation walls ofthelentire apparatus. In, this arrangement, drip-water from the ice house 61 is discharged into'the well 65 from a pipe 66, andfillsjthe well tothe level of the channel `67,""s` that the coil 64 is completely immersed at all times, and the cool air from the latter is discharged from the outlet pipe 68, immediately above the Water level and adjacent the entrance to said channel. In this form of the invention, it is also contemplated to utilize a portion of the cold air, after passing through the coils 60 and 64, at a distance, and for this purpose a branch pipe 69 is connected with the coil 64, and is provided With a valve 70, which s operable by means of a rod 71 extending upward to a convenient point for its manipula-tion.

It is to be understood 'that various changes in the detailed construction and arrangement may be resorted to Without departing from the spirit and scope of the invention, Having thus 'fully described the invention, what is claimed, is

1. In a cold storage apparatus, a main ice storage chamber, a cold storage chamber, means for maintaining an air circulation through said cold storage chamber, a plurality of auxiliary ice storage chambers, means for directing cold air from beneath said chambers into the auxiliary ice storage chambers, and means for utilizing the cold drip Water from said main ice chamber and said auxiliary ice chambers for cooling the air circulation of said apparatus.
